2020-10-15 Dense graded bituminous mixes such as binder and wearing courses are usually laid on a previously prepared bituminous layer. Binder course is the intermediate layer between bituminous base course and bituminous wearing course. Three different Specifications for dense graded bituminous mixes are available for use for airfield pavements.

2017-12-1 Introduction. Rutting is the main performance indicator for unbound aggregate base/subbase layers in flexible pavements. Several of the widely used rutting models, such as the one used in the Pavement ME Design software by AASHTO, predict the permanent deformation accumulation in unbound aggregate layers based on resilient strains levels without giving any consideration to aggregate shear ...
